Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30914, here are decompositions:

3 + 30911 = 30914
43 + 30871 = 30914
61 + 30853 = 30914
73 + 30841 = 30914
97 + 30817 = 30914
151 + 30763 = 30914
157 + 30757 = 30914
211 + 30703 = 30914

Showing the first eight; more decompositions exist.
